…treating our trading partners as allies rather than adversaries has paid enormous dividends for Americans. Just since 1990, world tariffs fell by nearly two-thirds as U.S. exports more than doubled, even after adjusting for inflation. …The Reciprocal Trade Act would turn this successful approach to trade on its head. …proponents who endorse this approach often argue that tariff reciprocity is needed to as a lever to reduce foreign trade barriers. But the White House’s own case studies show this is untrue. …Trump wants to replace a successful post-World War II policy based on the understanding that trade is win-win with one that is likely to encourage foreign governments to retaliate against Americans. …History shows trade policy is more likely to succeed if it is based on the Golden Rule instead of on hostile eye-for-an eye reciprocity. It turns out that the United States benefits when we treat our trading partners the way we would like them to treat us. …Princeton University’s Robert Keohane described how countries benefit from this “sequential reciprocity”… The goal of the Trump administration’s trade policy should be to promote reciprocal trade, not reciprocal taxes.

In an article for National Interest, Clark Packard also pours cold water on the Reciprocal Trade Act.

The United States Reciprocal Trade Act, which will soon be introduced by Rep. Sean Duffy (R-Wis.), would expand the president’s already enormous unilateral authority to impose tariffs and other import restrictions. …the Reciprocal Trade Act would grant the president the authority to match the tariff applied to any given product by a trading partner. To use one of the administration’s favorite examples, the Europe Union applies a 10 percent tariff on imported automobiles, while the United States levies a 2.5 percent tariff on its imports. The Reciprocal Trade Act would allow the president unilaterally to raise the tariff to 10 percent on European cars as leverage for further negotiations.

He lists some of the reasons why the proposed law is bad policy.

The bill is enormously flawed and should be a nonstarter for myriad reasons. …violates U.S. commitments to the WTO’s Most-Favored Nation (MFN) principle of nondiscrimination. …The bill also would violate U.S. commitments under Article II of GATT. …the effect of the law would be that countries would retaliate against American exports and ensnare unrelated industries in a tit-for-tat. …The United States has been successful in getting other countries to lower tariffs and other trade barriers through negotiations. …the Reciprocal Trade Act would jeopardize this American-led system that has paid enormous dividends.

All of his points are accurate, though I don’t expect the president’s supporters would care about violating WTO obligations since they presumably would cheer if Trump pulled the U.S. out of the the agreement – even though it has been very beneficial for the United States.

Now let’s look at the Congressional Trade Authority Act, which would restrict rather than expand the ability of the executive branch to impose higher taxes on trade.

…the Bicameral Congressional Trade Authority Act would ensure that all tariffs imposed by the executive branch in the name of national security must first be approved by Congress. Article I, Section 8 of the Constitution establishes that Congress “shall have the power to lay and collect taxes, duties, imposts, and excises.” The framers, in their wisdom, made this the very first power they delegated specifically to the legislative branch of the United States. Tariffs are taxes, and they adversely impact American consumers. Such measures should be enacted only after thoughtful debate by the elected representatives most accountable to the people of the United States. They should not be handed down unilaterally from the White House. …it’s time for Congress to reclaim their enumerated Article I power over trade. …FreedomWorks agrees with Rep. Gallagher and Sen. Toomey on the need to respect our Constitution and ensure Congress has full control over its Article I authority.

…some on Capitol Hill are trying again to rein in the President’s tariff powers. …the Pennsylvania Republican…Mr. Toomey’s bill would require Congress’s blessing. Once a tariff is proposed, lawmakers have 60 days to pass a privileged resolution—no Senate filibuster to block consideration—authorizing it. No approval, no tariff.This is a serious reassertion of the Article I trade powers that Congress has long shirked. Since the bill is retroactive, President Trump would have to convince Congress that his tariffs on steel and aluminum are necessary. If lawmakers didn’t agree, the tariffs would end. …But that’s not all. The Commerce Secretary is now responsible for declaring that an import endangers national security. This bill would give the task, sensibly, to the Defense Secretary.

I like what Senator Toomey is trying to achieve. And I like it, not only because I don’t want politicians interfering with trade, but also because I support the Constitution.

Interestingly, many Trumpies also claim to support the Constitution. Indeed, they are some of the biggest critics of the “administrative state,” which developed as federal agencies began to exercise legislative powers.
